get disk usage by file type

A simple and usefull script to evaluate usage of your disk by filetype. Should be improved
to manage extension with more than 3 letters. For this you can just replace the /\.{2,3}$/ by

/\..{2-6}$/ to accepts extension from 2 to 6 letters long.

#!/usr/bin/env zsh
if (($#<1)); then cible='.' else cible=( "$@" ) fi find $cible -type f -exec du -k {} \; | awk --posix ' { if ($2 ~ /\.[^/]{2,3}$/) { ext=$2; sub(/.*\./,"",ext); } else { ext="withoutExtension"; } taille[ext]+=$1 ; nb[ext]++ ; } END{ for (x in taille) { printf "%10d ", nb[x]; print x" for "taille[x]" Ko"; } }' | sort -n [/sourcecode] hope this is usefull
